Users with older Apple devices running iOS 9.3.5 can still download compatible apps by accessing their "Purchased" tab in the App Store, which often offers older versions of apps. For apps never previously owned, using a "bridge" device to download the app with the same Apple ID first allows the older device to download the last compatible version, according to YouTube tutorials.

For devices running iOS 9.3.5, the "solid feature" you likely need is the ability to download apps that officially require a newer version of iOS. Because most modern apps are incompatible with this legacy version, you can use the Last Compatible Version feature to get working apps. How to Install Apps on iOS 9.3.5

If you try to download an app and see an "Incompatible" error, follow these steps to trigger the download of an older, working version:

Access Purchases on the Old Device: Open the App Store on your iOS 9.3.5 device and go to the Purchased tab at the bottom.

Download the Legacy Version: Find the app in your list and tap the cloud icon. A popup will appear asking if you want to "Download an older version of this app?". Select Download. Recommended Apps for iOS 9.3.5

Media: VLC for Mobile is highly reliable for offline video playback.

Browsing: Puffin Web Browser often performs faster than the outdated Safari on older hardware.

Communication: Telegram usually offers a compatible version that remains usable.

  • Cause: Network glitch or Apple certificate expiration.
  • Fix: Go to Settings > Safari > Clear History and Website Data. Then, go to Settings > iTunes & App Store > Tap your Apple ID > Sign Out > Sign back in.

1. Introduction

On August 25, 2016, Apple released iOS 9.3.5 to patch three zero-day vulnerabilities (Trident exploit chain) used in targeted surveillance. For most users, it was a routine security update. For owners of the iPhone 4s and iPad 2, however, it became the final official operating system their devices would ever receive.

Today, in 2026, these devices are considered “vintage” by Apple (discontinued more than five years ago) and “obsolete” (discontinued more than seven years ago) in many regions. Yet thousands of these devices remain operational—used as dedicated music players, child-safe media consumption devices, home automation panels, or industrial controllers. For these users, the AppStore is not a convenience but a lifeline. This paper asks: What is the actual experience of using the AppStore on iOS 9.3.5 in the current era?
